You can get the wallpaper here: for-release-cartograph.png
As for those page indicators, the calendar, the "to-do" icon, all of those come with the theme. That is, if you bought it.
The foursquare icon is coming in a future release, I believe.
The dock is located on the Jaku repo. Just google search those exact words and you will find it.

Around these parts we like for people to do research in the thread where to find things. I know there are over 900 pages but a quick search in the forums should help you find anything you need. Now, if you have an issue with your device in terms of Jaku not working correctly or an icon request, a created icon you have made or just wanna show off your homescreen, please feel free to do so. If you see something in someones screenshot that you want or like, send that user a personal message

The foursquare icon (blue crown) is my personal mod of the Jaku 'Path' icon and the dock is also my mod and part of the wall.
With the remaining, you are right.
